This paper presents a multiphysics model specifically developed to be driven by optimization algorithms. The model establishes a link between electrical phenomena and electromagnetic noise in rotating electrical machines. The magnetic part is based on a meshed Magnetic Equivalent Circuit (MEC) that incorporates rotational effects and enables rapid computation of the radial pressure responsible for magnetic noise. The entire tool is implemented within an unified software environment, facilitating tight coupling between the physical model and the optimization process. A high-pole-count synchronous machine is used as study case to demonstrate the proposed approach.

The objective of this research is to develop a comprehensive optimization tool designed to identify low noise and vibration geometry for electrical rotating machines. This paper presents a meshing modelling method specifically developed for use in parametric optimization. A meshed Magnetic Equivalent Circuit is developed allowing to obtain the magnetic flux density in space and time, at any location on the machine. It also describes the functioning of the global tool, and provide some results related to the geometric model. The finality is to obtain the Maxwell pressure, which is causing noise and vibrations in electrical rotating machines.
